Specification of Letters Patent.

Patented May 11, 1909.

Application filed August 15, 1906. Serial No. 330,685.

To all whom it may concern:

Be it known that I, BENJAMIN F. BELLOV-FS, a citizen of the UnitedStates, residing at Cleveland, in the county of Cuyaliioga and State ofOhio, have invented a certain new and useful Improvement in. JustifyingMechanism, of which the following is a full, clear, and exactdescription.

This invention relates primarily to those parts of a linotype machine bywhich the lines of matrices are justified. It also includes somecooperative mechanism by which each line, when justified, is movedtoward the casting mechanism, and by which, at the proper time,saidcasting mechanism is set into operation or prevented from operating, as desired.

'l. he invention is an improvement upon the generic invention which isdescribed in my prior patent No. 727,267. It also resembles, in manyrespects, the justifying mechanism which formed the subject of my priorpatent No. 795,449, and is, in sense, an improvement upon thatmechanism.

lhe invention may be summarized as the combinations of parts shown inthe drawings and hereinafter described and definitely pointed. out inthe appended claims.

In the drawing Figure 1 is a front elevation of a part of a linotypemachine embodying the present invention, 2 is an enlarged frontelevation of a part of the justifying mechanism shown in Fig. 1. Fig. 3is a sectional plan view in the plane indicated by line DD on Fig. 1,thematrix assembling spout, and the mechanism associated therewith beingomitted from this figure. Fig. 4 is a full sized plan view of the arm 58attached to the space hey shaft and some mechanism associated therewith.Fig. 5 is a front elevation of one of the temporary spacers. Fig. 6 is aside view of one of the temporary spacers. Fig. 7 is a rear elevation ofthe mechanism shown in F ig. 3. Fig. 8 is bottom plan view of saidmechanism. 9 is a transverse vertical section in the p'ane indicated byline AA on Fig. 1. Fig; 10 is a front elevation of the lower ends of twospacer magazines and the upper ends of two of the spacer assemblingtubes associated therewith. Fig. 11 is a perspective view of the upperend of one of the spacer assembling tubes. Fig. 12 is a sectional planview of the electric signal switch mechanism. Fig. 13 is a transversevertical section in the plane of line B B on Figs. 2 and 3. Fig. 14 is aleft end 'iew of certain parts of the mechanism. Fig. 15 is a transversevertical section in the plane indicated by line (I O on Fig. '7. Fig. 16is a rear view of the right side of the members 170 and 195 and theoperative connections between said parts. Fig. 17 is a left side view ofthe connection between the members shown in Fig. 16, showing them in theposition they normally occupy. Fig. 1.8 is a similar view,showing theparts in the position they occupy when they have been renderedinoperative for transmitting motion from member 170 to member 195. Fig.19 is a front view of the mechanism for driving certain parts of thejustifying mechanism, the transverse slide and casting mechanism; thisView being taken in section ust behind the front plate of the supportingframe. Fig. 20 is a right side View of the cam shaft 150 and associatedparts. Fig. 21 is a rear elevation of the selooting plate and mechanismadjacent thereto. Fig. is a sectional side elevation of the parts shownin Fig. 21 the sectional line of the parts section being the line EE.

The mechanism shown in the drawing in which this invention is embodiedis, in many respects, substantially like the mechanism shown anddescribed in my prior patent No. 797,549. In order that the operation ofthe present invention may be understood, however, it will be necessaryto describe the construction of some of the mechanism which correspondswith that shown in said prior patent. That description will, however, beas brief as the conditlons will permit.

In assemliiling the matrix or type lines to be justified, the matrices11 (or type) are released, one hy one, from their respective magazines,and are delivered onto the assembling rail 1 t ough an assembling spout2. After each adchtion to a growing line on the assembling rail, theline is moved along said rail a distance equal to the width of the addition. The line may he so moved by a packer 15 which is constantlyreciprocated in a definite path. The packer and its operating mechanismmay be like that shown for the purpose in my prior patent 0. 800,971.

The permanent spaces 3 are stored in magazines 4, each of which has aplurality of channels 5 for containing spacers of different thicknesses.The front of the magazines 1s formed by a glass plate 140. Each spacerchannel has an independent escapement mechanism of some approved form,for releasing the spacers singly from said channels. Each of saidescapement mech anism must include an operating device as lever 101; andeach of said escapement operating levers is provided, on its under side,with a pin 102 adapted to be engaged by some of the pins 100 whichproject upward from the selecting plate 100. in the construction showneach escapement includes a pallet lever 98 which is provided with, aweighted horizontal tail piece 99; and the operating lever 101 engageswith this tail piece to operate it. The bottom claw 98 of the palletlever normally projects under the lowest space in the magazine channel,while the upper claw 98 is extended to enter a notch 3 in the space. Thefront part of lever 191 rests upon a fixed part of the frame of themachine; and its front end is directly behind a little shoulder 98 onthe pallet lever whereby the operation of the lever 98 is prevented,until the lever 101 is moved upward out of the path of said shoulder.

Each of the spacer magazines 4 has a contracted lower end whichcommunicates directly with a tube 6; and each of these tubes has atemporary spacer 7, flexibly connected with its lower end. The upper endof each tube has outwardly flaring sides 69 which bear againstdownwardly projecting ribs 57 located between the discharge mouths ofthe several magazines. On the rear side of the upper end of each tube isa rearwardly bent finger 61; and a flange 58 projecting down from thespacer magazine block goes between this finger and the rear part of thetube. The upper ends of tubes therefore lie below and are overhung bythe lower ends of the block in which said spacer magazines are formed;and the lower ends of the tubes may be moved as required withoutdisturbing this condition.

The temporary spacers 7 are not tubular as they are in the constructionshown in my prior patent. They are solid'metal blocks about half as highas a matrix; are quite a bit longer from front to rear than the width ofthe matrices. Their rear ends are flexibly connected with the rear sideof the associated tube 6. On top of the rear end of each spacer 7, is anotched ear 7 A bent arm 6 is connected with the rear side of the lowerend of each tube 6, and this arm and the ear 7 a are connected with aninterme diate piece 225 by pivots which are respectively at right anglesto each other. The described connection between the tubes and spacers isflexible to the required degree, because it permits the spacers toremain up right whether they are behind the assemnormal position. In therear end of each of these temporary spacers is a dove-tailed notch 8which permits said temporary spacers to be threaded onto the dove-tailedfront edge of the slide 9 when said spacers have been pushed forwardinto position over the assembling rail. T1888 temporary spacers are allof the same thickness, and this thickness is substantially equal to thewidth of the steps on the eliminator lever 7 8.

The only important differences between the mechanism above described andthat shown in my prior patent No. 797,549 is the substitution of solidtemporary spacers for tubular temporary spacers and their specificconstruction. the specific COIHLGClLlOIl between these spacers and thetubes 6; and the construction of the upper ends of the tubes and theparts immediately associated therewith whereby they maintain theiroperative relationship with the spacer magazine at all times.

Directly behind the assembling rail is a fixed guard rail 26 held insuch position that the temporary spacers may pass under it when they aremoved forward so as to extend over the assembling rail. The temporaryspacers rest upon the frame member 10 and normally lie in a compact rowbehind the assembling rail. A spring actuated spacer packer slide 12 isprovided with an' upwardly extended finger 13 which bears against theright end of said row and pushes the row to the left against the rightend of slide 9.

l 11911 the space key is depressed the left hand temporary spacer ispushed forward out of the described rank and into a position projectingover the assembling rail. The mechanism for causing this movement willbe presently described. Whenever the spacer is so moved forward out ofthe row the remaining spacers in the row are all moved to the left untilstopped by slide 9.

The detent slide 17 is movable in the horizontal path crosswise of themachine; that is to say, to right and left. It has in its top face aslot 16 which extends in a direction at right angles to the path of theslide (shown in dotted lines in Figs. 3 and 13) which receives adownwardly projecting rib 19 on the lower face of the detent 18 (seeFig. 13). This detent embraces the dovetailed front end of the slide 9(see Fig. 13), and, therefore, may move from right to left without therebeing any movement of the slide 9; but it must accompany the slide 9 inits lorward and backward movement. Vi hen the slide 9 is moved forwardthis detent extends over the assembling rail, but is drawn bacl;

bling rail or over it, or whether they are in unison with said slide toright or left. The or have been moved to the left out of their slide 9is moved backward and forward by edge a transverse notch 31.

means of a rock-shaft 173 carrying two arms 17 1. which are connectedwith said slide. This rock-shaft is moved in the direction which carriesthe slide forward by Deans of a spring. 175. This rock-shaft is alsoprovided with an arm 176. The upward movement of the rod 177 againstthis arm moves the rock-shaft in the direction which draws the slide 9backward.

Directly behind the left temporary spacer is a forwardly and backwardlymovable spacer inserting slide 30 having in its top This notch receivesa pin 65 on an arm 64 attached to a vertical rock-shaft 63. Whenever therockshaft 63 is rocked, the slide 30 is moved forward by the describedmechanism thereby pushing the left temporary spacer forward so that itsfront end extends over the assembling rail (see Fig. 1 1). The linepacker 15 then pushes this temporary spacer to the left a distance equalto the width of the spacer. When the slide 30 is drawn backward, thetemporary spacers remaining in the row are-all pushed by the tube packe12 to the left against the end of slide 9. When the spacer, which hasmoved forward into the assembling line, was pushed to the left by thepacker, its notch 8 slipped over and embraced the front edge of slide 9.

The space key 53 is connected with a rockshaft 51 to which is attachedan arm 52. This arm is connected by a link 54 with rocking detent 56.The upper end of this detent normally lies just below the front edge ofthe left end of the trough 67,which trough is pivoted at its right endto the frame of the machine, on a horizontal axis. Normally the left endof this trough is higher than the right end. There is a ball 68 in thistrough and when the detent 56 is withdrawn from beneath said troughthrough the operation of the space-key, the trough falls to an inclinedposition; andthe ball therein rolls down it, to the left, against thetail of a spring-actuated detent 69. This detent is pivoted upon an arm62 which is secured to the rock-shaft 63, and it normally engages with ashoulder on a spring pawl 71 which is pivoted to the same arm 62. Thisdetent acts to hold this pawl against the force of its spring, in such aposition that it will not be engaged by a shoulder 36 on the constantlyreciprocating slide 35. hen the ball, rolling down the trough strikesthe detent 69, it withdraws it from the shoulder 70, whereupon the pawl71 is moved by its spring into the path of the shoulder 36 on saidrecipro cating slide said slide to the right, this shoulder, by engagingwith the forward end of said pawl,

rocks rock-shaft 63, and thereby, through the described mechanism, theleft hand spacer is pushed forward. The rock-shaft 63 has another arm50' carrying a friction roller in its In the next movement of r end. Thetrough is provided with an inclined end wall 72 near its attached end.When rock-shaft 63 is rocked in the direction last described, this arm50, by engaging with the inclined wall 72 on the trough, rocks saidtrough back to its normal position. The ball thereupon rolls to theright against the wall 72. The space-key has in the meantime beenreleased. The spring on its rockshaft returns it to its normal position,and this carries the detent 56 beneath the trough, whereby the latter isheld up until again re leased by the operation of this space-key.

Vfhile the slide 35 is rocking the rockeshaft 63 in that direction whichcauses the spacers to be moved forward the pawl 71 while maintaining itsengagement with the shoulder 36 on slide 35 will be turned on its pivotenough to permit the detent 69 to again engage with the shoulder 70.Ffhen slide 35 again moves to the left, another shoulder 37 thereuponengages with the other end of the pawl 71 and thereby rocks therock-shaft 63 in the reverse direction back to its normal position.

The selecting plate 100 may be precisely like the selecting plate shownand described in detail in my prior patent No. 797 ,5 19. It is movablysupported upon the top of a pivoted frame 103, and is provided with arms10 1 which pass under and engage with the lower surface of the endmembers of said frame. It lies between and its ends are con nected withthe upper ends of the arms 107 attached to the rock-shaft 108 just as inmy prior patent No. 7 97,549. The roci shaft 108 is capable of rockingin its bearings; and it is subjected to the influence of a spring 113tending to rock it in that direction which will cause the rearwardmovement of the selecting pl'ate,-this spring 113 being attached to anarm 129, on said shaft. The shaft is also under the influence of thespring 109 tending to move it endwise in its bearings. The endwisemovement of said shaft is limited by the engagement of the pointed endof the shaft with the stepped wedge 91. The rearward movement of theselecting plate, when the shaft is permitted to rock under the influenceof its spring 113, is limited by the engagement of said selecting platewith the stepped wedge 85.

In nearly all of the respects above mentioned as well as in the specificform of the selecting plate itself the described mechanism issubstantially like the corresponding mechanism in my prior patent N o. 797,549. There are however two points of difference between the mechanismof that patent and the mechanism above described, viz; in the presentconstruction the shaft 108 has a pointed end which engages directly withthe stepped wedge 91, and the risers of this stepped wedge are inclined,wherefore the downward movement of this wedge block causes the varioussteps thereof to travel in contact with the shaft 108 and thereby saidshaft is moved endwise to return it to its initial position. Every timea temporary spacer is added to the line this stepped wedge moves upwarda distance equal to the width of one step, and this permits shaft 108 tobe moved by its spring distance equal to the height of one step; Theother difference is that whereas in the construc tion of the formerpatent the selecting plate was permitted to move rearward every time thestepped wedge 85 moved upward, in the present construction the selectingplate is restrained from any rearward movement whatever until saidstepped wedge has been moved upward as far as it is to be moved by theparticular line to be justified. This wedge is moved upward every timethe line is lengthened by the addition of a matrix after the line hasreached a predetermined length and this upward movement is due to themovement of the growing line along the assembling rail, after each.addition of a matrix to the line, a distance equal to the width of thataddition. This movement of the line is transmitted to the detent anddetcnt slide; from the latter to the stepped eliminator 78; from it tothe horizontally movable bar 70, and thence through lever mechanism tothe wedge. The line itself is moved by the line packer; and it sometimeshappens that the parts intermediate of the line and the wedge 85 acquireamomentum l ever, 1s not attached directly to the slide.

which will carry the wedge temporarily past the position which it shouldoccupy. If, as in. the former device, the selecting plate immediatelyfollows the wedge, the latter can.- not settle back to its properposition and hence the selecting plate becomes misplaced and thejustification. becomes imperfect. the present construction, however,that upward movement of the selecting plate which causes its pin toengage with pins on the escapement operating lever 1.01, is produced byupward pressure from a vertical bar 11.5. This bar is moved. down by aspring 106, which is secured to the lower mid of a bar 1 15 a to whichthe bar 115 is attached by means of an arm 11? and is moved up hy a'cam151 on the cam shaft l50,thc bar 115 being provided with an. arm 105cugaging with said cam. 'lhis bar 115 has near its upper end a disk orcollar 116 which engages upon the top of a crank pin 110 carried by anarm 111 attached to the rockshaft 108.

The described mechanism prevents the rock-shaft 108' from being rockedby its spring 113 and therefore prevents the selecting plate from movingrearward. But when the stepped wedge 85 has been. moved as far asnecessary in accordance with the length of the line to be justi'lied,the line key is depressed, and this, through mechanism to be presentlydescribed, causes the rotation of the cam shaft 150 and the consequentupward movement of the bar 1.1.5,-which movement is of course associatedby a like movement of the collar 116. This permits rock-shaft 108 to berocked by its spring, and thereby the selecting plate is carriedrearward until further rearward movement is prevented by itsengagementwith the proper step 011 the stepped wedge 85. il hen the cam shaftcompletes its rotation. it permits the spring 106 to move bar 115downward, and the collar 11.6, by engaging with said pin 11.0 rocks therec :-shaft 108 and thereby the selecting plate is returned to itsinitial position.

The upward movement of the selecting plate due to upward pressure frombar 115 is of course accompanied by the upward swinging movement of theframe 103. This frame carries a yoke bar 145 which extends over andengages with the tops of the rearwardly projecting tails 99 of theescapement levers. It is therefore impossible to operate one of theseescapement levers Without at the same time moving up this frame 103. Thedownward movement of the frame, draws this yoke bar 1.45 downward, andit positively draws down any of the escape ment levers which have beenoperated. while said frame was up.

The spacer packer slide 12 is, as stated, under the influence of aspring 41 tending to move it to the left. This spring, how- It isattached toone arm 44 of a three-arm lever 40. One of these arms 43 isprovided. with. an overhanging Inger 42 which. engages with the finger1.3 on the slide. Another arm 44 is connected with a vertically movablelink 90 whose upper end is con nected with one arm of a pivoted lever88, the other arm of said lever being connected to the stepped wedge 91.It is therefore evident that, when a temporary spacer is moved forwardout of the row in which. it normally stands, and said row is thereforemoved. to the left a distance equal to the spacer withdrawn from it,this lever 40 will swing and it will result, through the describedmechanism, in moving wedge block 91 up a distance equal to the width ofone of the steps thereon. This wedged block is .inovahle through aguide-way in a block 120 which is mounted in horizontal guide-ways whichare a part of the fixed frame of the machine. A set-screw 12]. passingthrough one member of this frame nears against the block 120 andfurnishes the means for very accurately adjusting its position, andconse uentl the aosition of the wed ed block 01 relative to shaft 108.The other arm 45 of the lever 40 is pivotally connected with the lowerend of a bar 74 in whose upper end is a curved slot 76. A link 75 whoselength is equal to the length of the lever arm 45 is ivoted to the frameand also to said bar. hythese means, the bar 7 4 is caused to movevertically whenever the lever is rocked, and to preserve .a positionparallel to its initial position, although it does not move in astrictly straight line.

The horizontally movable bar 7 9 is pivotally connected to the upperends of two parallel pivoted levers 80 and 81. Qne of these levers hasan arm 83 to which the lower end of the tail 84 of wedge 85 is pivotallyconnected. A stepped lever 78 whose function is to serve as aneliminator, is pivoted to the bar 7 9. The width of the varions stepsthereon is equal to the width of each of the temporary spacers. Thesteps of this eliminator project into the path of a lever 21 pivoted tothe rear face of a block 22 which is adjustably secured to the detentslide 17. This block consists of two parts 22, 22 adjustably securedtogether, by a set-screw 24 and the block as a whole is adjustablysecured to the detent slide by set-screw 23. This block is madeadjustable so as to adapt the mechanism for justifying lines of variouslength, the said block being placed at such point on the detent slidethat it will, at the proper time, come into contact with whichsoever ofthe steps on the eliminator 78 is in the path of said lever 21. The ste)ped lever eliminator extends on both sides of its pivot. That arm whichis opposite to the arm carrying the wedge steps is provided with a pin77 which enters a slot 76 in the vertically movable bar 7 1. The lowerend of this bar is pivotally connected with the arm 45 of the lever 40,which lever it will be remembered, rocks a definite distance every timea temporary spacer is pushed out of its waiting rank into a growingline. of said lever causes a corresponding vertical movement of bar '74and this movement is sufficient to so rock the stepped eliminator leveras to bring another step thereon in the plane of the lever 21. Whenthereafter the line is moved along a distance equal to the width of thetemporary spacer added the detent slide receives. a correspondingmovement, but this movement does not cause any movement of the bar 7 9because, by reason of said movement of the stepped eliminator lever, thedetent slide must move a distance equal to the width of said spacebefore the lever 21 again comes in contact with the new step on theeliminator lever which has been moved into its path. The addition ofmatrices to the line will cause a corresponding movement of the detentslide, and it will, through the described mechanism, cause acorresponding movement of the endwise movable bar 79, and thesemovements will be transmitted through the lever arms 81 and 83 to thevertically movable stepped lever 85. Whenever the line is ready to beThis movement I position that when the selecting plate is allowed tomove back into contact with it said selecting plate will be in aposition -to release a permanent space from each magazine whose deliverytube 6 has been moved forward; and the aggregate width of the s acers soreleased will he exactly equal to t 1e line shortage.

Having now described mechanism by which the justifying mechanism is set,I will now describe the means whereby the spacers are released anddelivered into the line and all the parts returned to their initialposition, and the justified line moved on toward the casting mechanism.The operating mechanism includes a number of cams attached to a normallynon rotating cam shaft 150; and suitable clutching mechanism forconnecting this cam shaft to a rotating element. Loosely mounted. uponthis cam shaft is a ratchet 152 attached to a gear 153, which is to beconstantly rotated. One of the cams 15 has a pawl 155 pivoted to it;this pawl being attached. to a roclnshaft 156 to which also an arm 157is attached. This arm is normally engaged by a lever 158 attached to arock-shaft 160. An upwardly extended arm 161 is also attached to therock-shaft 160, and this arm is connected with a trans versely movableslide 32 located just below the assembling rail. This slide has a notch33 in it, into which, normally, an arm 126, attached to the line key125, projects. By depressing the line hey this arm is withdrawn fromsaid notch whereupon the slide is moved to the left by the action of aspring 162 upon the rock-shaft 160. The movement of the rock-shaftwithdraws the lever 158 from its engagement with the arm 157 on the pawlrock-shaft, whereupon said pawl flies into engagement with the ratchet152 and the cam shaft immediately begins to revolve. llhere are six camsupon this cam shaft. The first of these cams to become affected is thecam which engages with the arm 105 on the vertically movable bar 115.This bar is thereby moved upward, and consequently the connected bar 115is similarly in ved with the result of first raising disk 1 16 so as topermit rock-shaft 108 to be turned by its spring, and thereby to carrythe selecting plate into contact with the stepped wedge 85. The furtherupward movement of this bar 115 brings it against the selecting plateand moves the same upward so as to operate the proper escapements andrelease the proper permanent spaces, which thereupon fall down throughthe tube 6 and take their places on top of the temporary spacers 7 inthe line. There is a \/shaped groove 7 b (see Fig. 5) in the tops ofthese spacers, and the permanent spaces come to rest upon the temporaryspacers, with their lower endsin said groove. As this cam 162 continuesits justified this stepped wedge will be in such a l revolution it willpermit spring 106 to draw bar 115 down and thereby the selecting platewill be moved forward by the mechanism described, to its initialposition.

During the upward movement of bar 115 the arm 117 attached theretoengages with the rear end of arm 95 attached to a rock shaft 94. A guardplate 93 is attached to the front end of said arm 95. The upwardpressure of this arm 1.17 turns the rock-shaft so as to swing this guardplate down in front of the assembling rail, whereby the permanentspaces, when they fall onto the temporary spacers will remain in theline instead of bounding forward out ofthe same. A spring 96 acts toturn this rock-shaft 95 in the reverse direction, when it is permittedto so turn by reason of the downward movement of the bar 1.15. The nextcam to become operative is the cam 163 by means of which slide 9 isdrawn backward. This cam engages with an arm on the vertically movablebar 177. The cam is so formed that be fore it imparts any upwardmovement to said bar it ermits the bar to be moved downward s ightly bya spring 178 and this is for the purpose of operating mechanism whichwill move the detent slide to the left a short distance. The mechanismfor doing this consists of the pivoted lever 180 having in one end aslot 181 which takes over a pin 17 9 on the rod 177. A weighted pawl 182is pivoted to this lever for engagement with ratchet teeth on the underside of the detent slide. By the downward movement of the rod 177 thislever is so rocked that the pawl thereon by engaging with said ratchetteeth will move the detent slide to the left. This relieves the line ofall endwise pressure which might tend to close the gaps therein left bythe withdrawal of the temporary spacers, and therefore allows thepermanent spaces to drop down onto the assembling rail when thetemporary spacers are withdrawn. The rod 177 is next moved upward bythis earn 163, and in its upward movement it rocks rock-shaft 17 3, soas to draw slide 9 backward and thereby withdraw the detent and thetemporary spacers backward out of the line. This same upward movement ofthe rod 177 swings lever 189 so that pawl 182 is entirely withdrawn fromthe range of the ratchet teeth of the detent slide. rail 26 prevents thepermanent spaces from moving back with the temporary spacers.

While slide 9 is in its rearmost position described the detent slide ismoved to the right, back to its initial position. The detent is carriedwith it, and this detent by engaging with the temporary spacers 7 whichare embracing the front edge of slide 9, moves said spacers off of theend of said slide and holds them disengaged from the slide until theslide moves forward again. This retracting movement of the detent slideis ac complished by means of a lever 183 (see Fig.

The guard 7) having a forked upper end which embraces a pin 14 on thedetent slide. This lever is pivoted and is provided with an arm 186which engages with a cam 165 attached. to the cam shaft. After thismovement, the line transfer slide 25 is moved to carry the justifiedline off of the assembling rail toward the casting mechanism. The slideitself is substantially like the slide shown in my prior patent. It ismoved, however, by a lever 191 which is connected with said slide by alink 192. This lever has an arm .198 which. is engaged by a cam 166. Thecam moves the lever in the direction which causes the transfer slide tocarry the justified line to the casting mechanism. A spring 19 1 movesit in the opposite direction. While these operations have been going ona cam 154 has engaged with an arm 159 attached to the lever 158 andthereby said lever has been rocked to position in which its end willengage with the arm 157 on the rock-shaft of the pawl 155 and therebywithdraw said pawl from engagement with the ratchet when the cam shafthas made one revolution. The described movement of this lever has alsorocked the rock-shaft 160 so that the slide 32-2 is returned to thatposition where its notch 33 may be engaged by the arm on the line key.There is one other cam 167 on the cam. shaft 150 whose function is toset the casting mechanism in operation whenever a justified line hasbeen moved by the transfer slide into the embrace of said. castingmechanism. The casting mechanism itself is not shown. It is however tobe driven by a constantly rotating shaft 187 to which a ratchet 188 isat tached. A gear 189 loose upon this shaft carries a pawl 190forengagement with this ratchet, and this pawl is connected with arock-shaft 184 mounted in gear and having an arm 185 projecting into thepath of one arm of lever 195, which is loosely hung on rock-shaft 196. Abar 170 having fork 171 in its lower'end, embraces a groove 169 in theearn 168 and carries a friction roller 17 adapted to engage with a cam168. The upper end of this bar has a pin 164 engaging in a substantiallyvertical slot 197 in lever 19:". This lever carries a spring pawl 198which normally lies in the path of the upper end of the 1.70. Just asthe cam shaft 150 is completing its rotation, cam 168 moves the 39.1 170endwise and this bar by engaging with saidv pawl 198 swings lever 195 onits pivot and thereby releases pawl 190. A spring 199 thereupon swingsthe ml 190 into engagement with the ratchet 188; and. thereupon thedriving mechanism of the casting mechanism begins to rotate.

It sometimes happens however that one does not wish the castingmechanism to operate to make linotype from an assembled line. Means areprovided for preventing the starting of the casting mechanism wherebythe line may go past itwithout beingsubject- I come in contact with, andwill have moved.

ed to its action.

This mechanism consists of i one arrn of a pivoted bell crank lever 136.

a rock-shaft 200 having an operating arm or j The vertical arm of thislever is connected key 201 by which the operator may manually rock saidrock shaft, and having also another arm 202 which occupies such positionthat it may engage the pawl 198 on lever 195, and

by so engaging with it may push it out of the 1 plane in which the upperend of bar 170 moves. When it is so pushed, a spring detent 203 fliesbehind it and keeps it in said withdrawn position. The movement of thehas then no effect upon the lever 195; but when said bar 170 movesdownward it will turn slightly upon pin 164 as a pivot, and its end willengage with this detent 203 and withdraw it, and thereby the pawl 198will be moved by its spring 198 back to its initial position. The pawl198 is prevented from going beyond said initial position by a pin eitherby springs which have been described or by mechanism positively operatedfrom said cam shaft which will now be referred to.

The downward movement of the stepped wedge 91 causes the movement ofshaft 108 back to its initial position. The power to so move the steppedwedge downward is taken from rock-shaft 173 and is transmitted throughthe following chain of mechanism, to wit; an arm 149 fast to said shaft,and projecting forward therefrom into a slot 147 in a link 146 pivotallyconnected with the same arm of lever 40 to which the upwardly extendedbar 90 is connected. This slot in the link is of such length that itdoes not interfere with the downward movement of said lever arm 149through the six step by step movements which it receives as thetemporary spacers are moved out of their row into the growing line. i lhen however the rockshaft is rocked for the purpose of drawing slide 9rearward the said arm will move into engagement with the upper end ofsaid slot and will thereafter pull upward on the link with sufficientforce to rock the lever and thereby to push upward on the link 90,whereby the lever 88, is rocked and the stepped wedge 91 moved downwardto its initial position with the result of moving shaft 108 back to itsinitial position.

When the tail piece 90 is moved downward six steps, as it will be,through the described niechanism, when the six tubes shown have beenmoved forward into the l l l growing line, a finger 89 thereon will havel with a horizontally movable bar 137 which is connected with the lowerend of a detent lever 138 which normally occupies an inactive position.?Ihen, however, the bar is moved in the manner described this detentlever is swung so as to take a position beneath a toe 66 on the balltrough 67. If now the space key 53 is depressed the trough will not fallbut will be upheld by this debar 170 due to the action of cam 168thereon,

tent lever. inere will consequently be no movement of those parts, whosemovement is initiated when the trough drops and the ball therein rollsdown against the detent 69. A rearwardly extended arm 58 is attached tothe space key rock shaft. 1%. lever 46 is pivoted upon this arm, and hasan upwardly extended finger 47 which extends into the path of the end ofthe bar 137. A spring 48 engaging with this lever tends to spring it soas to maintain the engagement between the finger 47 and bar 137. l i'hen the bar 137 is moved endwise by the rocking of the bell crank 136,it swings this lever 46 on its pivot, and thereby carries the end ofsaid lever beneath a projection 143 on a vertically movable rod 142which is provided for operating the escaperrent of a magazine containinga spacer of the average width for use in justifying a line. Thedepression of the space key therefore after all of the tubes have beeninserted in the growing line will cause the release of a permanent spacefrom one of the socalled matrix channels, and said space will beassembled in the line just as matrices are when they are released.

It is desirable that the operator be able to determine at any time thelength of the line he is assembling,-or more exactly the length whichthe line would have if justified. For this purpose a transverselymovable scale 27 is suitably supported in front of the assembling rail.The heads of screws 29 screwing into the frame member 10, fit ahorizontal dovetailed groove 28 in the rear face of said scale. If thisscale were absolutely stationary it would merely show the length of theline made up of matrices plus the total width of the temporary spacerstherein. These spacers however are always considerably larger than thepermanent spaces which the justified line will contain. To know thelength of the line containing temporary spacers is not what is requiredby the operator. This scale is therefore movable, and it is moved withthe line whenever a temporary spacer is put into the line. This movementof the scale is not however equal to the width of the temporary spacer,but is equal to the difference between the width of the temporary spacerso added, and the width of what may be called the standard space, thatis to say, a spacer such as will give the ideal spacing between words.The left end of the line will therefore always be opposite to agraduation upon this scale which shows the actual length which the lineas then composed would have if it were spaced with. said standard space.To effect this movement of the scale rock-shaft 3% is provided havingtwo arms,one 38 which has a crank pin 39 engaging in the vertical slot49 in the rear face of the scale. The other arm 82 has a crank pin 87engaging in a horizontal slot in an arm 73 connected to the verticallymovable bar 90 which, it will be remembered, moves down a definite distance every time a temporary spacer is ad ded to the line. The leverarms upon this rock-shaft are so proportioned that the scale will move,as before stated, every time a temporary spacer is added to the line, adistance equal to the difference between the width of the spacer soadded and a standard justifying space.

It is also desirable that a signal be dis played when the line isnearing completion; and, preferably, this signal should be displayed theinstant the line beomes capable of being justified by the describedmechanism. In the machine illustrated in the drawing, mechanism isprovided for giving a signal at this preferred time. The signal 226 maybe a lamp, a bell, or a buzzer, or any other device capable of beingrendered operative by the completion of an electric circuit. Themechanism shown consists of two binding posts 210 and 211 to beconnected with the terminals of the signal circuit, and which areelectrically connected with two springs 212 and 213. Two levers 214i and215 respectively carry near their rear ends insulated. pins 216 and 217.The two springs bear respectively against these pins, and obviously whenthese pins come in contact the circuit will be closed. These two leversbear at their front ends respectively upon two shelves 92 which arerespectively secured to the ver tically movable members 84 and 90. itwill be remembered that the bar 90 moves down a short distance everytime a space is added to the line; and this movement will. permit such amovement of the lever 21 32 that the pin 216 thereon will be moved.toward the pin 217. It will also be remembered that as the line islengthened by the addition of matrices thereto rod 84 moves upward; andthis permits such a movement of the lever 215 that the insulated pinthereon 217 will be moved nearer to the pin '21 6 on the other lever.This obviously is aproper movement, because by the addition of matricesalone the line would evidently get long enough to be justified if onlyby the addition of one spacer. It is also obvious that two contact pinsshould be brought nearer together by each addition of a temporary spacerto the line because the more permanent spaces there are to be added tothe line the shorter may be the line made of matrices alone in order tobe justifiable. The capability of the line to be justified is dependentnot only on its length made up of matrices alone but by the number ofspacers which must be employed for justiiication. The closure of theelectric circuit which renders the signal operative is, because of theconstruction above described, dependent upon these two factors.

In Fig. 21, the switch closing mechanism for the signal is shown in aposition which indicates that the line is nearly ready to be j ustiiied.
